In the face of climate change, the scientific community, particularly in the IPPC Sixth Assessment Report published in 2022, in confirming the key role played by cumulative greenhouse gas emissions and in collectively achieving carbon neutrality. While we must focus on drastically reducing the world's use of fossil fuels if we are to limit global warming, there is no single path to achieving this goal. Indiscriminately reducing the supply of all fossil fuels, without first developing the capacity for low-carbon alternatives, would align supply with demand, triggering inflation and deepening social inequalities. So everyone – governments, producers and consumers – will have to collectively mobilize to ensure the emergence of a planetary market for decarbonized energy sources.
